Chronological List of District Heating
Systems in the United States |
The Missoula Mercantile Company built a large heating plant in their new building in 1890 that provided heat for their own building and others nearby.
This plant was replaced with a larger plant built in 1902 in a separate building. This new plant was sold to the Missoula Light and Water Company in 1906 and was acquired by the Missoula Public Service Company in 1925 and then by the Montana Power Company in 1929.
Montana Power Company
discontinued steam service in March 1960.

Evidence introduced at a hearing July 15 at the Missoula County Courthouse
revealed that the number of customers served dropped from 179 at the end
of December 1958 to 93 at the date of the hearing, including 16 in the
process of converting to gas.
Conversion has continued until today only about 54 customers remain,
reported Harry McCann, Missoula Division manager. At the peak of
operations, it had approximately 200 customers, he said.
It was brought out in the hearing that the rapid decline has been due to
the fact that natural gas is from 30 to 40 per cent cheaper than the cost
of steam heat. It was further stated that, although conversion to gas
results in additional original expenditure, the original cost will be
recovered through fuel cost savings within one to four years in the
majority of situations.
The official added that the company personnel will assist all of the steam
customers, in every way possible, to get their heating systems changed
over in order to meet the closing date set by the commission.
McCann said the plant, which is a Missoula landmark, was established about
a half-century ago. It was purchased by the Montana Power Co. from the
Missoula Public Service Co. in 1929. Rates now in effect for the service
were established by the Montana Railroad and Public Service Commission in
1950.
The plant houses five steam boilers which generate steam through 6.3U0
feet of mains, and approximately 3,900 feet of service connections in the
central business district. Four firemen are employed full time, and meter
reading, bookkeeping and other admin istrative activity is conducted at
the firm's offices in the Masonic Temple Building on East Broadway.

The plant was built in 1902 by the Missoula Mercantile Co. to serve its
own requirements and those of three or four other nearby buildings.
On Jan. 1, 1906 the plant was acquired by the interests of William A.
Clark, one of the Butte copper kings, under the name of the Missoula Light
& Water Co.
The Clark interests sold the operation to the Missoula Public Service Co.
in 1925 and Montana Power acquired it in 1929.
